I am running current Norton Security. I got a pop-up with Norton symbol at upper left. "Internet Explorer Protection Alert. Some of the Norton protection features are not enabled on Internet Explorer. Enable Norton to protect your device and your identity when you surf Internet Explorer." Button to "Enable now." I did not click Enable now. Instead, I opened Norton and everything is green. What does the popup mean? Is it a true Norton message? And should I Enable? Running Windows 7 Pro 64 bit. Please help.
